Abstract: A light fixture delivers light to an illuminated space. The light fixture includes a housing that defines a skylight aperture therethrough, and movable louver blades coupled within and spanning the skylight aperture. Open, the louver blades do not substantially block light through the skylight aperture; closed, the louver blades block substantially all light through the skylight aperture. In intermediate positions, the louver blades block a portion of light through the skylight aperture. The light fixture also includes a dimmable artificial light source, integrated with the housing and configured to project light toward the illuminated space; a light sensor; and a control unit that is integrated with the housing and communicatively coupled with the light sensor. The control unit receives a signal from the sensor, and controls position of the louver blades and brightness of the artificial light source, in response to at least the signal from the light sensor.
